The skies were cloudy today. When I set up the solar rig, there were cirrus clouds over most of the sky without any significant clearings (aka sucker holes). I set up anyway and shot through the gossamer clouds. My results were adequate, I suppose.
Today’s H-alpha image shows a lot of prominence activity along the NW and SW solar limbs. There is also prominence activity along the SE limb. Activity along the NE limb where a dark filament touches the solar disk’s rim, is very faint.
The corresponding sunspot image shows four active regions including two new sunspot groups along the eastern side of the disk – AR4089 and AR4090. AR4088 is now faint and about to go around to the sun’s far side. AR4089 on the eastern limb is also quite faint even in today’s NASA SDO (Solar Dynamics Observatory) image.
The solar prominences are highlighted in the galleries below.
